  However, since the shower head is located on the upper side and the spout is located on the lower side with respect to the user of the faucet, if the push buttons are arranged in parallel in the horizontal direction, the shower head and the spout are presented to the user. It is difficult to grasp the correspondence between the button and the push button. That is, if the push buttons are arranged in the vertical direction so as to correspond to the vertical position relationship between the shower head and the spout, it is easy to grasp the correspondence relationship between the push button and the valve unit. However, when configured in this way, the valve units also need to be arranged in the vertical direction so that the valve units can be smoothly opened and closed by a push-down operation of the push button. Therefore, the faucet becomes long in the vertical direction and the design is not only impaired, but also the space below the faucet becomes narrow and difficult to use.

  The present invention has been made paying attention to such problems existing in the prior art. The purpose is to realize a faucet that is excellent in design and easy to use.

  In order to achieve the above object, the present invention provides a faucet in which a driven portion of a valve unit is pushed by a push-down of a push button that is rotated about an axis to execute water discharge and water stop. The shaft is disposed at a position facing the driven portion in front of the driven portion in the operation direction, and the changed operation is performed by changing the operation direction of the push button between the push button and the driven portion. An operation direction changing mechanism for transmitting to the driven part is provided.

  If comprised as mentioned above, even if the operation direction of the push button arrange | positioned ahead of the driven part of a valve unit is a direction different from the operation direction of a driven part, the driven part of a valve unit can be operated smoothly. it can. Therefore, even when the push buttons are arranged in the vertical direction in a configuration in which a plurality of valve units are arranged in the horizontal direction, the valve units can be smoothly switched. For this reason, it is possible to make the faucet horizontally long and easy to use with excellent design.

  According to the present invention, it is possible to realize a faucet that is excellent in design and easy to use.

Hereinafter, an embodiment of a faucet embodying the present invention will be described with reference to the drawings.
3 is connected to a water supply pipe (not shown). As shown in FIGS. 1 to 3, the main body 11 is covered with a cover 12, and the cover 12 includes an upper cover piece 121 and a lower cover piece 122 that are coupled to each other. A connection part (not shown) to which a shower head (not shown) is connected via a hose (not shown) is provided at the upper part of the rear part of the main body 11. A connecting portion 13 for connecting a spout (not shown) is provided at the lower portion of the main body 11.

  As shown in FIGS. 3 and 4, a first valve unit 21 and a second valve unit 22 are juxtaposed in the lateral direction in the main body 11. The first valve unit 21 is for switching between water discharge from the shower head and water stop. The second valve unit 22 switches between water discharge from the spout and water stop. The first and second valve units 21 and 22 are provided with driven buttons 23 and 24 as driven parts. These driven buttons 23 and 24 are push-operating operation formulas operated in the front-rear direction, and the water discharge state is switched and set by being pushed for the first time, and the water stop state is switched and set by being pushed for the second time. .

  As shown in FIGS. 6 and 8, an arc-shaped cam surface 241 is formed in the lower half of the front surface of the driven button 24 of the second valve unit 22 so that the lower side retreats and the upper side advances.

  As shown in FIGS. 1, 5, and 7, the first push button 31 is located at the center of the front upper portion of the upper cover piece 121 in the lateral direction above the first valve unit 21. The shaft 32 is supported so as to be rotatable in the vertical direction. The shaft 32 is located above the first valve unit 21. As shown in FIG. 4, a push leg 33 is formed to protrude downward on the back side of the right end portion of the first push button 31, and the tip thereof faces the driven button 23 of the first valve unit 21 on the shower side. doing.

  In this state, due to the weight of the first push button 31 and the push leg 33, the lower end portion of the push leg 33 comes into contact with the front surface of the driven button 23 in a natural state, and in this state, on the operated surface of the first push button 31. A certain upper surface is almost horizontal with a slightly lower front. Then, as indicated by an arrow in FIG. 5, the operation direction of the first push button 31 is a downward direction, and the first push button 31 is pushed down and rotated downward about the shaft 32 to thereby move the driven button. 23 is pushed backward by the pushing leg 33, and the driven button 23 is switched to a water discharge or water stop state.

  As shown in FIGS. 1, 6, and 8, at the lower side of the first push button 31 and at the lateral center of the front portion of the upper cover piece 121, A second push button 34 is supported at the front position so as to be rotatable in the front-rear direction on the shafts 35 on both sides thereof. As shown in FIG. 4, a pushing leg 36 having a substantially fan shape is formed on the back side of the left end portion of the second push button 34 so as to protrude downward in the rear portion. A roller 37 is supported so as to be rotatable. Then, due to the weight of the second push button 34, the outer peripheral surface of the roller 37 is in contact with the lower portion of the cam surface 241 of the driven button 24 in the natural state. As shown in FIG. 6, in this state, the front surface, which is the operation surface of the second push button 34, is inclined upward, and the pushing direction of the second push button 34 is directed backward as indicated by the arrow direction. It is diagonally below.

  As shown in FIG. 8, the shaft 35 of the second push button 34 is disposed at a position facing the lower half of the front surface of the driven button 24 of the second valve unit 22, that is, in front of the moving direction of the driven button 24. The lower half of the driven button 24 that faces in the direction parallel to the central axis C of the driven button 24 is located in the upper part of the projection plane F.

  Then, the second push button 34 is pushed down and rotated obliquely downward on the rear side about the shaft 35, whereby the roller 37 rolls upward on the cam surface 241. As a result, the driven button 24 is pushed backward by the cam action of the cam surface 241 to switch to the water discharge or water stop state. Therefore, the cam surface 241 constitutes an operation direction changing mechanism for converting the movement direction of the second push button 34 and pushing the driven button 24. If the cam button 241 is not formed on the front surface of the driven button 24 and the front surface of the driven button 24 has a planar shape orthogonal to the central axis C, the roller 37 is moved by pressing the second push button 34 down. The driven button 24 can be pushed in slightly, but the second valve unit 22 is not switched to the water discharge state or the water stop state.

Therefore, the faucet of the present embodiment operates as follows.
When the first push button 31 is pushed down so as to be pivoted about the shaft 32 in the water stop state of the shower, the driven button 23 is pushed in via the push leg 33 and the shower enters a water discharge state. Further, when the first push button 31 is pushed down again, the driven button 23 is pushed in again through the push-in leg 33 and the shower is stopped.

  Further, when the second push button 34 is pushed down obliquely downward so as to rotate about the shaft 35 in the water stop state of the spout, the roller 37 rolls upward on the cam surface 241 of the driven button 24. However, the driven button 24 is pushed in by the cam action, and the water is discharged from the spout. Further, when the second push button 34 is pushed down again, the driven button 24 is pushed again by the cam action as described above, and water discharge from the spout is stopped.

  As described above, in the present embodiment, in the configuration in which the first and second valve units 21 and 22 are arranged in the horizontal direction, the first and second push buttons 31 and 34 are arranged in the vertical direction. In addition, since the first and second push buttons 31 and 34 are pushed downward or obliquely downward, the water can be discharged and stopped easily. That is, even if the first and second valve units 21 and 22 are arranged side by side in the lateral direction, the push leg 33 extends downward toward the first valve unit 21 in the first push button 31 located on the upper side. Therefore, the laterally driven button 23 of the first valve unit 21 can be pushed in without difficulty. On the other hand, the second push button 34 located below the first push button 31 and on the front side of the second valve unit 22 is also operated downward. For this reason, it is difficult to push the driven button 24 of the second valve unit 22 located substantially at the same height as the first valve unit 21 backward by the pushing leg of the first push button 31, and it can be pushed in temporarily. However, a strong pushing force is required, which is not only difficult to use, but also a high load acts on a part such as the periphery of the shaft 35, and there is a risk of breakage unless a strong reinforcement is applied to the part.

  In this case, the first and second valve units 21 and 22 are juxtaposed in the vertical direction, and the positional relationship between the second push button 34 and the second valve unit 22 is determined between the first push button 31 and the first valve unit 21. If the same positional relationship is used, the above-described problems can be solved. However, since the first and second valve units 21 and 22 are arranged side by side in the vertical direction, the water faucet has a vertically long shape. become. For this reason, the design of the water faucet is lowered, and the user's foot becomes narrow and inconvenient. On the other hand, since the faucet of this embodiment becomes horizontally long, such a problem does not arise.

In this embodiment, the following effects can be obtained.
(1) When the first push button 31 is pushed downward, the driven button 23 of the first valve unit 21 is smoothly pushed by the push leg 33. Even if the second push button 34 located on the front side in the pushing direction of the second valve unit 22 is pushed down obliquely, the driven button 24 is smoothly pushed backward by the action of the cam surface 241 of the driven button 24. Accordingly, the first and second push buttons 31 and 34 can be juxtaposed in a vertical direction different from the juxtaposition direction of the first and second valve units 21 and 22. In other words, even if the first and second push buttons 31 and 34 are arranged in the vertical direction, the second push button 34 positioned in front of the second valve unit 22 is smoothly pushed down similarly to the first push button 31. It can be operated and is easy to operate.

  (2) Therefore, even if the first and second valve units 21 and 22 are juxtaposed in the horizontal direction, there is no problem in operation, and the entire faucet is formed in a horizontally long shape with excellent design. In addition, the user's feet are not narrowed, and an easy-to-use faucet can be realized.

  (3) And in embodiment, the 1st push button 31 for switching the water discharge and water stop of the shower supplied from the upper side with respect to a user from the upper side of the cover 12 from the lower side with respect to a user. A second push button 34 for switching between spout water supply and water stoppage is provided at the bottom. Accordingly, the user can intuitively recognize the correspondence between the first push button 31 and the shower and the correspondence between the second push button 34 and the spout at a glance. Accordingly, the faucet can be easily used.

  (4) Since the roller 37 rolls on the cam surface 241 of the operation direction changing mechanism, there is almost no frictional resistance between the cam surface 241 and the roller 37. Therefore, the second push button 34 is smooth. You can get action.

(Example of change)
In addition, this embodiment can also be changed and embodied as follows.
As shown in FIG. 9, the shape of the cam surface 241 of the driven button 24 of the second valve unit 22 is changed to a linear slope.

  -Instead of the roller 37 of the second push button 34, the tip of the pushing leg 36 should be in direct contact with the cam surface 241. In this case, it is desirable to coat at least one of the pressing leg 36 and the cam surface 241 with a material having a small friction coefficient such as a fluororesin.

As shown in FIG. 10, contrary to the above embodiment, the driven button 24 is provided with a roller 38 and the pushing leg 36 is provided with a cam surface 361.
-The axis 35 of the second push button 34 is positioned below the projection plane F. In this case, as shown in FIG. 8, the angle of the line C1 connecting the centers of the shaft 35 and the shaft 371 of the roller 37 with respect to the front surface 341 of the second push button 34 is increased, but the same effect as in the above embodiment is obtained. be able to.

  Contrary to the above, the axis 35 is positioned above the projection plane F. In this case, the same action as in the above embodiment can be obtained, but the cam surface 241 of the driven button 24 is preferably provided in the upper half of the driven button 24.

  -The present invention is embodied in a faucet having one or three or more push buttons and valve units.
